0031137: Modeling Data, BinTools_ShapeSet - avoid allocation of temporary arrays

BinTools_ShapeSet now defines maps with proper types instead of Standard_Transient.
BinTools_ShapeSet now avoids allocation of temporary arrays while reading
triangulation and polygonal data.

Classes Poly_Triangle, Poly_PolygonOnTriangulation, Poly_Polygon3D and Poly_Polygon2D
have been cleared from .lxx files and extended by new methods for preallocating and filling array,
as alternative to passing arrays by copy.

wavefront command - export "f" instead of obsolete "fo" keys into file.
BinTools - added missing tools for reading/writing short reals.
